Anyone who believes in free markets and free trade has to believe as a corollary in the free movement of people. Guido is the son of immigrants who came from Ireland and India to London in the 1950s and 1960s for economic and social reasons. They came, primarily, to better themselves. Now having lived and worked in some of the world’s greatest cities Guido still believes that London is the best of them all and is grateful that the city took in his parents.

Sure the roads are congested, they are in Tokyo and New York as well. Culturally New York is very self-centred and less internationalist, Tokyo is a bit of a mono-culture that just about tolerates foreigners. London is much more cosmopolitan than even New York with better French food than Paris, more bankers than Frankfurt and better nightlife than Berlin. Many people have come here without the right paperwork, they have come here to work and better themselves. They are not the problem and should be allowed to stay and given if necessary an amnesty to make them legally resident. They enrich us all. It is the people who come here to abuse the welfare state and commit crimes that are the problem.

Cameron disavows the policy and ConservativeHomies are up in arms about Boris supporting an amnesty for illegal immigrants. They should remember that one of their heroes, Ronald Reagan, supported and implemented an amnesty. London should be a beacon to those who want to be free to prosper for themselves and their families. Disqualifying newcomers from abusing the welfare state and deporting convicted foreign criminals might reduce the opposition to immigrants. Ronald Reagan did something like that when he had an amnesty for immigrants in 1986, because to him, the ultimate conservative optimist, immigration was a vital part of his vision of his country as “a shining city upon a Hill”.

Boris is an optimist in the Reagan mould who would like London to be a shining city for those seeking freedom and prosperity. An amnesty might not be a popular stance to take, illegal immigrants don’t have any votes, but it is the right stance.
